Waste Management Flashcards
What waste are suspected to contain pathogens e.g. laboratory cultures; waste from isolation wards; tissues (swabs), materials, or equipment that have been in contact with infected patients?
Infectious waste
Identify the kind of waste.
Human tissues or fluids e.g. body parts; blood and other body fluids; fetuses
Pathological waste
Identify the kind of waste.
needles; infusion sets; scalpels; knives; blades; broken glass
Sharps
Identify the kind of waste.
laboratory reagents; film developer; disinfectants that are expired or no longer needed; solvents
Chemical waste
What is the trash bin color of infectious waste?
Yellow
What is the trash bin color of sharps waste?
Red
What is the trash bin color of radioactive waste?
Orange
Identify the waste treatment.
Uses heat but in the absence of oxygen in a destruction chamber where the waste is converted to gas, liquid, or solid form.
Pyrolysis
Identify the waste treatment.
- Steam sterilization (wet thermal disinfection).
- Usual setting is 121°C with a pressure of 15 psi for 15 to 30 mins.
Autoclave
Identify the waste treatment.
- Temperature of 100°C for at least 30 minutes.
- Microorganisms are destroyed by moist heat which irreversibly coagulates and denatures enzymes and structural proteins.
Microwave
Identify the waste treatment.
Enzyme mixture to decontaminate wastes.
Biological process
Identify the waste treatment.
Filling of containers with waste and sealing the containers.
Encapsulation
Identify the waste treatment.
Suitable for pharmaceutical waste that involves the mixing of waste with cement and other substances before disposal.
Intertization
What are the usual temperature and pressure settings when treating wastes with autoclave?
121* Celcius
15psi
What is the usual temperature setting when treating wastes with a microwave?
121* Celcius
